Gardeners' Notes:

Positive noseykate On Feb 1, 2015, noseykate from SOUTH WEYMOUTH, MA wrote:

I have two of these hydrangeas, which overwintered in the bitter 2013-14 cold with no problem. They were covered with blooms, at first a clear sky-blue and then changing to purple and on to deep burgundy which lasted into fall. This hydrangea (and the similar "Tiny Tuff Stuff") has become my favorite of the varieties that I grow. Vigorous and very beautiful.

Neutral coriaceous On Dec 9, 2014, coriaceous from ROSLINDALE, MA wrote:

This is advertised as the first reblooming lacecap hydrangea. Because it blooms on both old and new wood, bud blast or dieback from exceptionally cold winters should not wipe out bloom the following summer. (Bloom time is from early summer till fall.)

Flower color depends on soil pH, pink on alkaline (high pH) soil to blue-purple or blue on acid (low pH). The big showy sterile outer florets are semi-double to fully double.

According to the originator, at maturity this shrub is 2-3' tall and wide.

This plant is hardier than indicated above, to Z5a.

The cultivar name is 'MAK20'. "Tuff Stuff" is a proprietary trade name.


This plant has been said to grow in the following regions:
